74dcb37ec3 vmm: config: fix incorrect values of error
The PR #2333 added I/O rate limiter on block device, with some options
in `DiskConfig`.  And the PR #2401 added rate limiter on virtio-net
device with same options, but it still throws `Error::ParseDisk`.

This commit fixes it with correct values.

01900e3c2b vmm: properly set vcpu state when thread exited
Once error occur, vcpu thread may exit, this should
be critical event for the whole VM, we should fire
exit event and set vcpu state.

If we don't set vcpu state, the shutdown process
will hang at signal_thread, which is waiting the
vcpu state to change.

0567def931 vmm: config: Avoid closing invalid FDs from 'test_net_parsing()'
We need to provide valid FDs while creating 'NetConfig' instances even
for unit tests. Closing invalid FDs would cause random unit test
failures.

Also, two identical 'NetConfig' instances are not allowed any more,
because it would lead to close the same FD twice. This is consistent
with the fact that a clone of a "NetConfig" instance is no
longer *equal* to the instance itself.

b14427540b vmm: config: Close FDs for TAP devices that are provided to VM
These are owned by the config (and are duplicated before being used to
create the `Tap` for the virtio-net device.)

By implementing Drop on NetConfig we have issues with moving out of
members that don't implement the Copy trait. This requires a small
adjustment to the unit tests that use the Default::default() function.

1143d54ee0 tpm: Add recv timeout while running recvmsg
If swtpm becomes unresponsive, guest gets blocked at "recvmsg" on tpm's
data FD. This change adds a timeout to the data fd socket. If swtpm
becomes unresponsive guest waits for "timeout" (secs) and continues to
run after returning an I/O error to tpm commands.

b54ce6c3db vmm: Defer address space allocation
We can ideally defer the address space allocation till we start the
vCPUs for the very first time. Because the VM will not access the memory
until the CPUs start running. Thus there is no need to allocate the
address space eagerly and wait till the time we are going to start the
vCPUs for the first time.

5b3bcfa233 vm-migration: Snapshot should have a unique SnapshotDataSection
There's no reason to carry a HashMap of SnapshotDataSection per
Snapshot. And given we now provide at most one SnapshotDataSection per
Snapshot, there's no need to keep the id part of the SnapshotDataSection
structure.

0489b6314e tdx: Support new way of declaring memory resources
Without breaking the former way of declaring them. This is simply based
on the presence of the GUID TDX Metadata offset. If not present, we
consider the firmware is quite old and therefore we fallback onto the
previous way to expose memory resources.

b173f6f654 vmm,devices: Change Gic snapshot and restore path
The snapshot and restore of AArch64 Gic was done in Vm. Now it is moved

The benefit is that the restore can be done while the Gic is created in
DeviceManager.

While the moving of state data from Vm snapshot to DeviceManager
snapshot breaks the compatability of migration from older versions.

b62a40efae virtio-devices, vmm: Always restore virtio devices in paused state
Following the new restore design, it is not appropriate to set every
virtio device threads into a paused state after they've been started.

This is why we remove the line of code pausing the devices only after
they've been restored, and replace it with a small patch in every virtio
device implementation. When a virtio device is created as part of a
restored VM, the associated "paused" boolean is set to true. This
ensures the corresponding thread will be directly parked when being
started, avoiding the thread to be in a different state than the one it
was on the source VM during the snapshot.

ec01062ada vmm: Switch order between DeviceManager and CpuManager creation
The CpuManager is now created before the DeviceManager. This is required
as preliminary work for creating the vCPUs before the DeviceManager,
which is required to ensure both x86_64 and aarch64 follow the same
sequence.

It's important to note the optimization for faster PIO accesses on the
PCI config space had to be removed given the VmOps was required by the
CpuManager and by the Vcpu by extension. But given the PciConfigIo is
created as part of the DeviceManager, there was no proper way of moving
things around so that we could provide PciConfigIo early enough.
